DEVICE OF CONTROLLED CYCLIC SHIFT Russian patent published in 2011 - IPC G11C19/00 

FIELD: information technologies.

SUBSTANCE: device of controlled cyclic shift includes n data inputs, n data outputs, m≤log₂n bit inputs of a control code and clock pulses input, input data register with n data inputs, forming data inputs of the device, clock pulses input electrically connected to input of device clock pulses, at the same time the input register is electrically connected with n data outputs to inputs of switching matrix, formed by switches arranged along n lines and m levels and having a bit input of a control signal, the first and second data inputs and a data output.

EFFECT: provision of possibility for a high-speed cyclic shift of information by m positions per signal clock cycle of an external clock frequency generator.
